Tunneling effect on composite fermion pairing state in bilayer quantum Hall system
arXiv:cond-mat/0112473 · doi:10.1103/PhysRevB.65.115319
Abstract
We discuss the composite fermion pairing state in bilayer quantum Hall systems. After the evaluation of the range of the inter-layer separation in which the quantum Hall state is stabilized, we discuss the effect of inter-layer tunneling on the composite fermion pairing state at ν=1/2. We show that there is a cusp at the transition point between the Halperin (3,3,1) state and the Pfaffian state.
